I recently ordered this 8X2X1 Arkansas Translucent stone from a reputable supplier and it was advertised as "1st grade". After thinking about the brownish streak running thru both sides of the stone, I question if they possibly sent me a "2nd". I would think after paying a premium price, the stone would be clear and free from any discolorization although I may be wrong.
I have emailed the supplier and await their reply, but in the mean time wanted to see what y'all think the definition of "1st grade" quality is.
